Nikki Rothwell of Michigan State University's Northwest Michigan Horticulture Research Centre talks about spotted wing drosophila (SWD). Unlike other fruit flies that target mostly rotting or fermenting fruit, SWD targets fruit right on the tree, laying their eggs in the young fruit and eventually turning it into a wormy mess. SWD targets a wide range of crops including cherries, apricots, plums raspberries, currants, and elderberries. The bad news is that spotted wing drosophila is spreading across North America, benefiting from our warming climate. Nikki has found that there are ways to make our orchards less hospitable for SWD. Simple tools like pruning and orchard floor maintenance are a large part of the equation.
